Alright, there is a temporary workaround for the problem. But you have to change the authentification settings on your XP/2k box...

Here is how to do that:

Start -> Run "secpol.msc"
In the tree open and click Security Settings -> Local Policy -> Security Options
Scroll the left pane down to 'Network Security: LAN manager authentication level'
Change this to 'Send NTLMv2 response only'

I think this is the last step required for me to finally switch off my Windows box. I have all my photos hosted on my Mini now, but my wife needs access to them and she couldn't get at them from her Windows machine.

Okay, it's a work-around - but it works for me!

Brilliant, thank you very much indeed!

EDIT - for those of you like me who have just got this fixed thanks to evilJazz, you might find Sharepoints quite useful. Allows you to easily add other shared folders on your Mac for you Windows machines to talk to.

EDIT 2 - Oh, forgot to mention, for me the preference pane applet didn't work. I had to use the application version. Not too worried, but just thought I should mention it in case others just tried the preference pane version, had the same problem and gave it up as a waste of time._________________My Flickr
